The Honda 31706-ZA1-812 Insulating Bush (6MM) is a genuine OEM component designed for EW140, EW170, EW171, and EXW171 welder generators. As a direct Honda OEM part, it is manufactured to the exact specifications of the original, ensuring a correct drop-in fit with no guesswork. Confirm your unit's serial number against the fitment table before ordering, as Honda periodically supersedes components at production breaks.
Key Features
- Genuine OEM Electrical Isolation — sourced directly from Honda, this insulating bush provides the dielectric separation the electrical assembly requires, maintaining the integrity of the circuit it serves in EW-series welder generators.
- Exact 6MM Sizing — the 6MM designation identifies this specific variant; verify this matches the bush your unit requires before purchasing, particularly if multiple sizes are listed for your model.
- Broad EW-Series Coverage — fits the EW140, EW170, EW171, and EXW171 welder generators; check your serial number against the compatibility table to confirm the correct application for your specific unit.
- Direct Replacement — this genuine Honda part installs in place of the original with no adaptation, restoring the electrical isolation function the assembly depends on.
An insulating bush is a small but electrically critical component used to isolate a conductor, terminal, or fastener from an adjacent metal surface, preventing unintended electrical contact. In a welder generator — which simultaneously produces generator power and welding output — maintaining clean electrical separation at connection points is essential to safe and consistent operation of both circuits. When this bush cracks, deforms, or degrades, the insulation it provides breaks down, which can result in intermittent faults or unwanted continuity between components that must remain electrically isolated.
